What are the coil packs numbered as?

That car uses a waste spark system so one coil covers cylinders 1 and 4 the other is 2 and 3 as shown in the image. What codes do you have? With that coil pack system, you usually lose 2 cylinders when they fail because each coil fires both cylinders on it at the same time. It also doesn't matter which wire is on which terminal so as long as 1 and 4 are on their coil you could put them on in reverse and it won't matter. So, 1-4 or 4-1 doesn't matter. Same with 2-3 or 3-2. The firing order is 1-3-4-2 The wires on the other hand can be an issue.
